%%  REVISION HISTORY:
%%
%%  v1.6: 2003-Apr-14  Charles S. Wilson
%%      * caption labels: OGS requires (e.g.) 'Figure 2:' to be in
%%        same font as rest of caption (bold ok, changing font not ok)
%%      * make vita double-spaced
%%      * fixed a bug in Signature page when no Committee Chair.  Thanks
%%        Arnaud Cottet for reporting it.
%%      * Changed one-and-a-half spacing to better match the description
%%        in The LaTeX Companion (use 1.25, not 1.33).
%%  v1.5: 2002-Aug-17  Charles S. Wilson
%%      * COMPLIANCE: new documentation
%%      * caption labels: make them prettier
%%      * Change gatech-thesis-gloss.sty to handle real glossaries;
%%      * NEW: gatech-thesis-losa.sty now handles the List of Symbols
%%  v1.4: 2002-Aug-03  Charles S. Wilson
%%      * Better handling of equation, table, and figure numbering
%%        (added David Carlisle's \@removefromreset macro, and use
%%        that instead of the previous kludge.)
%%      * Corrected problem with two-sided printing: the even-numbered
%%        (left hand) page between the end of \preliminary and the
%%        beginning of the first chapter was not printed.  This really
%%        messed up duplex printers.  FIXED.
%%      * Corrected problem when vita (or whatever the last section
%%        before \end{postliminary}) was \included instead of \inputted.
%%      * Signature page no longer prints empty lines for non-existent 
%%        committee members.  Also, uses two columns if more than 4
%%        members, per the Graduate Office Guidelines.  AND we no longer
%%        print its page number
%%      * Now uses (requires) the calc package, which is part of the
%%        standard latex installation.
%%      * Automatically center the dedication (but see the new functions
%%        \dedicationtop and \dedicationbottom
%%      * Correctly doublespace the title on both titlepage and signaturepage
%%      * page numbering defaults to a centered footer, as per the new
%%        Graduate Office guidelines
%%      * Added proper handling for multiple volumes in a single thesis
%%      * Added support for the add-on styles ``gatech-thesis-gloss.sty''
%%        and ``gatech-thesis-index.sty''.
%%  v1.3: 2002-Jan-13  Charles S. Wilson
%%      * Renamed to gatech-thesis at request of the CTAN folks.
%%  v1.2: 2001-May-01  Charles S. Wilson
%%      * Minor tweaks to conform to latest GSO requirements
%%  v1.1: 2001-Apr-29  Charles S. Wilson
%%      * Fixup to work nicely with pdflatex and hyperref
%%  v1.0: 2001-Jan-24  Charles S. Wilson
%%      * Initial release: merged UT-THESIS.STY with GTthesis.sty
%%        and gt-thesissty.sty.
%%
%%  KNOWN BUGS:
%%
%%   - FIXED: (sortof) [On ``dedication'' and ``acknowledgements''
%%     causing an error when they both appear on the same page.]
%%     GT style doesn't allow these to appear on the same page,
%%     so \begin{dedication}...\end{dedication} will ALWAYS
%%     appear on its own page.  Ditto acknowledgements.
%%
%%   - I didn't fix this; GATECH-THESIS.CLS has inherited this bug
%%     from UT-THESIS.CLS: [On missing page headers for float pages.]
%%     ``teTex'' under Linux fails in precisely the same way as does
%%     ``MikTeX'', so there's something clearly wrong somewhere, but
%%     I don't know where.  It only fails on odd-numbered pages (if
%%     you remove enough text so that the page floats back to an
%%     even-numbered page, the page header is correct)!

%% OLD:  
%% OLD:  REVISION HISTORY:
%% OLD:  
%% OLD:  v1.8: 1999/12/10 (Francois Pitt)
%% OLD:      - Fixed circular definition problem with \currenttextsize
%% OLD:        that caused TeX to run out of input stack memory.
%% OLD:  v1.7: 1999/06/02,1999/05/20,1999/05/13 (Francois Pitt)
%% OLD:      - Minor change to the format of the date printed on every
%% OLD:        page with the ``draft'' option.
%% OLD:      - Minor cosmetic change to the word ``DRAFT'' printed on the
%% OLD:        corners of every page with the ``draft'' option.
%% OLD:      - Made ``draft'' mode doublespaced by default (it just makes
%% OLD:        more sense for actual drafts; suggested by Eric Joanis).
%% OLD:      - Changed \currenttextsize from a ``\newcommand'' to a ``\let''.
%% OLD:      - Added ``known bugs'' above.
%% OLD:  v1.6: 1999/03/06 (Francois Pitt)
%% OLD:      - Minor change: replaced ``\ifx\empty#1\else...\fi'' with
%% OLD:        ``\ifx\empty#1\empty\else...\fi'' (the former works only
%% OLD:        by accident while the latter is logically correct).
%% OLD:  v1.5: 1999/02/17 (Francois Pitt)
%% OLD:      - Fixed missing page numbers and headers by removing
%% OLD:        redefinition of \cleardoublepage (reported by Robert
%% OLD:        Bernecky 1999/02/04 and Nedialko Nedialkov 1999/02/12).
%% OLD:      - Added \clearemptydoublepage and \clearplaindoublepage
%% OLD:        commands.
%% OLD:      - Removed redefinitions of \tableofcontents, \listoftables,
%% OLD:        and \listoffigures because they already call \clearpage
%% OLD:        or \cleardoublepage by default.
%% OLD:      - Removed ``\setcounter{tocdepth}{2}'' from the page layout
%% OLD:        section (moved to ``ut-thesis.tex'' where it belongs).
%% OLD:      - Added \ignore command to comment out parts of a file.
%% OLD:      - Put version macros at the top of the file.
%% OLD:      - Changed order of revision comments.
%% OLD:  v1.4: 1998/11/05 (Francois Pitt)
%% OLD:      - Fixed ``abstract'' environment so that it is really put on a
%% OLD:        separate page, and changed ``\newpage\endgroup'' at the end
%% OLD:        to ``\par\endgroup\newpage'', which is more logical.
%% OLD:      - Changed ``acknowledgements'' environment so that it is *not*
%% OLD:        put on a separate page, allowing users to add other text
%% OLD:        on that page (e.g., ``dedication'' described next).
%% OLD:      - Added ``dedication'' environment based on ``acknowledgements''
%% OLD:        (suggested by Robert Bernecky 98/11/04).
%% OLD:      - Changed page layout so that it is defined in terms of the
%% OLD:        physical page size instead of being hard-coded for letter
%% OLD:        paper (8.5" x 11").
%% OLD:  v1.3: 1998/11/01 (Francois Pitt)
%% OLD:      - Fixed ``thebibliography'' so page headers are generated in
%% OLD:        the same style as for the rest of the thesis.
%% OLD:      - Swapped \endgroup and \newpage in definition of ``abstract''
%% OLD:        and ``acknowledgements'' environments, to fix problem with
%% OLD:        adjusted line spacing in ``abstract''.
%% OLD:      - Renamed ``\currentsize'' to ``\currenttextsize''.
%% OLD:      - Added \cleardoublepage at the end of preliminary sections,
%% OLD:        so that page 1 of main text is on right-hand side.
%% OLD:  v1.2: 1998/10/20 (Francois Pitt)
%% OLD:      - Changed ``spacenotes'' option to ``spacednotes'' to have more
%% OLD:        consistently named options.
%% OLD:      - Fixed spacing between main text and footnotes.
%% OLD:      - Fixed ``singlespaced'' environment, which didn't seem to
%% OLD:        work at all (reported by Nedialko Nedialkov 98/10/12):
%% OLD:        Actually, created a ``newspacing'' environment, which takes
%% OLD:        a parameter, and based ``singlespaced'', ``oneandahalfspaced'',
%% OLD:        and ``doublespaced'' environments on ``newspacing''.
%% OLD:  v1.1: 1998/10/01 (Francois Pitt)
%% OLD:      - Fixed bug that caused footnotes to make following tables
%% OLD:        single-spaced (reported by Philip Edmonds 98/09/30).
%% OLD:      - Made spacing of marginal notes and footnotes the same.
%% OLD:      - Added option to control line spacing of notes.
%% OLD:      - Added options to control the size of margins.
%% OLD:      - Changed names of temporary macros used in redefinitions
%% OLD:        to avoid conflicts with existing names.
%% OLD:  v1.0: 1998/09/29 (Francois Pitt)
%% OLD:      - Initial version.

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%%  
%%  LaTeX2e class file for formatting documents according to the
%%  Graduate Studies' guidelines for theses at the Georgia Institute 
%%  of Technology. 
%%  
%%  USAGE:  \documentclass{gatech-thesis}
%%          \documentclass[...options...]{gatech-thesis}
%%  
%%  The default settings produce a final copy, ready for submission
%%  (11pt font, single-sided, double-spaced, normal margins,
%%  with single-spaced notes).
%%  
%%  OPTIONS:
%%  
%%   - Any standard option for the LaTeX2e ``report'' class, including
%%     ``10pt'', ``11pt'', ``12pt'', ``oneside'', ``twoside'', etc.
%%  
%%   - ``singlespaced'', ``oneandahalfspaced'', or ``doublespaced'':  Set
%%     the entire document's default line spacing, except for notes,
%%     which are single-spaced by default.
%%  
%%   - ``spacednotes'':  Let the line spacing of notes be determined
%%     by the line spacing of the main document, instead of being
%%     forced single-spaced.
%%  
%%   - ``narrowmargins'', ``normalmargins'', ``widemargins'', 
%%     ``extrawidemargins'' or ``oldmargins'':  Set the size of 
%%     the margins, as follows:
%%      . ``normal'': 1 1/2" on left, 1" on top, right and bottom
%%        headers & footers 1/4" from body;
%%        - This is the Georgia Tech standard
%%      . ``narrow'': 1 1/4" on the left, 3/4" on all other sides,
%%        headers & footers 1/4" from body;
%%      . ``wide'': 1 1/4" on all sides, headers & footers 3/4" from
%%        body;
%%      . ``extrawide'': 1 1/2" on all sides, headers & footers 3/4"
%%        from body.
%%      . ``oldmargins'': 1 1/2" on left and top, 1" on right and bottom
%%        headers & footers 1/2 from body;
%%        adds 2"" extra space from top of page, on the first
%%        page of a chapter or appendix.
%%        - This is the OLD Georgia Tech standard
%%     (If you have more than just a few marginal notes, it is
%%     recommended that you use ``wide'' or ``extrawide'' margins.)
%%     Use ``normalmargins'' (the default) for the approved GT format.
%%
%%   - ``draft'':  Produce a draft copy (10pt font, double-sided,
%%     double-spaced, normal margins, with the word "DRAFT" printed
%%     at all four corners of every page, and current date printed in
%%     a running footer).
%%
%%   - ``hyperref'': Indicates that the document will \usepackage{hyperref}.
%%     This is a kludge, but I didn't want to explicitly *require*
%%     hyperref, so we must indicate to gatech-thesis.cls whether it should
%%     define certain hyperref commands as dummies.  ALWAYS use this
%%     option if you use the hyperref package.  NEVER use this option if
%%     you do not also use the hyperref package.
%%  
%%  Note that these options can be used to override the default or
%%  draft document settings, so that it is possible, for example,
%%  to create a double-sided final copy, or a 1 1/2-spaced draft
%%  copy with wide margins, etc.  Also note that when producing
%%  double-sided documents, new chapters and preliminary sections
%%  will always start on a right-hand page under the default
%%  settings (inserting a blank page if needed), but not if the
%%  ``draft'' option was used.  (This can be overriden by using the
%%  ``openany'' or ``openright'' options.  To achieve this effect for
%%  individual sections or chapters, use the \cleardoublepage
%%  command.)  Note that the blank page inserted in these cases will
%%  still contain the header and page number that is present on all
%%  pages.  For ``empty'' or ``plain'' pages, explicitly use one of the
%%  commands \clearemptydoublepage (totally blank inserted pages),
%%  \clearplaindoublepage (blank except for page number at bottom), or
%%  \cleartcplainfdoublepage (blank except for page number at Top
%%  Corner (hence, TCplain).  You can also explicitly use 
%%  \cleargtthesisdoublepage (but I don't know why you would, since this
%%  only makes sense if the current pagestyle is already gtthesis, and
%%  if that is the case then you're better off just using \cleardoublepage.
%%  
%%  NEW ENVIRONMENTS and COMMANDS:
%%   in some cases, there will be two commands with identical
%%   effect.  These are usually because one is needed to maintain
%%   compatibility with documents that expect the old macros from
%%   GTthesis.sty.
%%  
%%   * \title{...}:  (preamble only; REQUIRED)
%%
%%   * \author{...}:  (preamble only; REQUIRED)
%%     Specify the name of the author.
%%
%%   * \department{...}:    (preamble only; REQUIRED)
%%   * \dept{...}:          compatibility synonym
%%     Specify the name of the graduate department.
%%
%%   * \degree{...}:  (preamble only; REQUIRED)
%%     Specify the name of the degree (e.g., "Doctor of Philosophy").
%%  
%%   * \gradyear{...}:      (preamble only; REQUIRED)
%%   * \copyrightyear{...}: compatibility synonym
%%     Specify the year of graduation (defaults to current year).
%%
%%   * \principaladvisor{...}:  (preamble only; OPTIONAL)
%%     (or \principaladviser{...}, if you prefer advisor spelled with an e)
%%
%%   * \committeechair{...}: (preamble only; OPTIONAL)
%%
%%   * \firstreader{...}:    (preamble only; OPTIONAL)
%%   * \secondreader{...}:   (preamble only; OPTIONAL)
%%   * \thirdreader{...}:    (preamble only; OPTIONAL)
%%   * \fourthreader{...}:   (preamble only; OPTIONAL)
%%   * \fifthreader{...}:    (preamble only; OPTIONAL)
%%   * \sixthreader{...}:    (preamble only; OPTIONAL)
%%
%%   * \submitdate{month year in which submitted}
%%     date is LaTeX'd if not specified
%%
%%   * \titlepagetrue or \titlepagefalse
%%     - produce or don't produce a title page (TRUE by default)
%%
%%   * \signaturepagetrue or \signaturepagefalse
%%     - produce or don't produce a signature page (TRUE by default)
%%
%%   * \copyrighttrue or \copyrightfalse
%%     - place or don't place a copyright notice on the title page (FALSE by default)
%%
%%   * \figurespagetrue or \figurespagefalse
%%     - produce or don't produce a List of Figures page (TRUE by default)
%%
%%   * \tablespagetrue or \tablespagefalse
%%     - produce or don't produce a List of Tables page (TRUE by default)
%%
%%   * \contentspagetrue or \contentspagefalse
%%     - produce or don't produce a Table of Contents page (TRUE by default)
%%
%%   * \bibpagetrue or \bibpagefalse
%%     - produce or don't produce a Bibliography page (TRUE by default)
%%
%%   * \thesisproposaltrue or \thesisproposalfalse
%%     - indicate "Thesis Proposal" or "Thesis" on the title page (FALSE by default)
%%
%%   * \dedicationheadingtrue or \dedicationheadingfalse
%%     - display ``DEDICATION'' heading on the dedication page (FALSE by default)
%%
%%   * \dedicationtop and \dedicationbottom
%%     - The Graduate Office Guidelines say that the dedication should be centered
%%       on the page.  By default, this is done -- but IMO it looks ugly.  The
%%       vertical spacing above and below your text is proided by these two
%%       macros; redefined them if you want to do something different.  E.g.
%%       this looks nice:
%%         \renewcommand{\dedicationtop}{\vspace*{\stretch{1}}
%%         \renewcommand{\dedicationbottom{\vspace*{\stretch{3}}
%%       which places the dedication about 1/4 of the way down the page.
%%
%%   * \strictmarginstrue or \strictmarginsfalse
%%     - if true, then obey the margin rules EVEN on the title and signature
%%       page. Default TRUE and REQUIRED by Graduate Studies Office, but
%%       not very appealing.  (under ``oldmargins'' an extra 50p spacing is
%%       added so that the title page looks like the chapter headings
%%       In any case, \strictmarginsfalse looks better for personal copies
%%       but \strictmarginstrue is necessary for official ones.
%%
%%   * \multivolumetrue or \multivolumefalse
%%     - if true, indicates that the thesis will span multiple volumes. 
%%       triggers automatic generation of the first volume title page
%%       (in addition to the ``entire work'' title page), but it's up
%%       to you to place the ``part{}'' commands in the appropriate
%%       locations for volume 2, volume 3, etc.
%% 
%%   * \bibfiles{...}
%%    Set the list of bibfiles to use when generating a bibliography   
%%  
%%   - \linespacing{...}:  (preamble only)
%%   - \spacing{...}:      compatibility synonym
%%     Set the interline spacing directly, overriding document
%%     defaults and options; note that in order to get the correct
%%     appearance, the argument to \linespacing must be equal to
%%     1/3 + 2/3 times the desired line spacing (for example,
%%        single-spaced = \linespacing{1},
%%         1 1/2-spaced = \linespacing{1.25}, and
%%        double-spaced = \linespacing{1.66}).
%%
%%   - ignore{...}:
%%   - comment{...}:     compatibility synonym
%%     Ignore the part of the file between { and } (can include
%%     paragraph breaks); useful for commenting out large blocks.
%%  
%%   - \clearemptydoublepage, \clearplaindoublepage, 
%%     \cleartcplaindoublepage, \cleargtthesisdoublepage
%%     Same as \cleardoublepage except that it sets the pagestyle of
%%     any inserted blank page to ``empty'' ``plain'' ``tcplain'' or
%%     ``gtthesis'' respectively.
%% 
%%   - \begin{preliminary}...\end{preliminary}:
%%     Delimit head matter (title page, abstract, table of contents,
%%     lists of tables and figures, etc.): set the page style and
%%     numbering for the preliminary sections and reset them for the
%%     main document.
%%    + Alternatively, at the appropriate spots call the synonums 
%%      \beforepreface and \afterpreface.  These ``synonyms'' do
%%      the same setup tasks as \begin{preliminary} and \end{preliminary},
%%      but they don't create an ``environment.  The use of these
%%      synonyms is NOT recommended for new documents and are provided 
%%      only for backward compatibility.
%%
%%      - \beforepreface:
%%        Sets pagestyle and generates titlepage (via \maketitle)
%%        and signature page (via \makesignature) if indicated.
%%        DON'T call directly in new documents.  Use \begin{preliminary}
%%        instead.
%%
%%      - \afterpreface:
%%        Sets pagestyle back to normal, restarts page numbering
%%        DON'T call directly in new documents.  Use \end{preliminary}
%%        instead.
%%  
%%      - \maketitle:
%%        Generate the title page from the information supplied
%%        in the preamble.  Called automatically by \begin{preliminary}
%%        or \beforepreface.
%%
%%      - \makesignature:
%%        Generate a signature page from information supplied 
%%        in the preamble.  Called automatically by \begin{preliminary}
%%        or \beforepreface.
%%  
%%      - \begin{dedication}...\end{dedication}:
%%        Generate a dedication section, if needed.
%%  
%%      - \begin{acknowledgements}...\end{acknowledgements}:
%%        Generate an acknowledgements section, if needed.
%%
%%      - \begin{abstract}...\end{abstract}:
%%        Generate the abstract page.
%%  
%%      - \begin{summary}...\end{summary}:
%%        Generate a summary page (same as abstract, but different
%%        heading)
%%
%%      - \begin{preface}...\end{preface}:

%%          is a nice touch IMO for the body and endmatter, but

%%        - note that you also need to add \pagestyle{gtthesis}
%%          if you use \setbodypagestyle{gtthesis}.
%%
%%      + Chapter headings and the TOC use ROMAN numerals, but
%%        the running headers at the top of each page use ARABIC
%%        numbers for the Chapter number.  Thus, there are two
%%        separate formats that are used.
%% 
%%        - \thegtchapter is used for ROMAN chapter numbers
%%        - \thechapter is used for ARABIC chapter numbers
%%
%%        If you wish all chapter headings to use ROMAN, then just
%%        redefine \thechapter in your document:

%%%%%%    Page Styles

%% Redefine all four standard page styles (empty, plain, headings,
%% myheadings), based on the definitions in ``report'', so that they
%% conform to the GSO guidelines (and include draft information if
%% applicable).
%%
%% Also, define a new pagestyle ``tcplain'' which is just like ``plain'',
%% but puts page numbers in header (left/right 2page, or right 1page)
%% instead of at the bottom of the page.
%%
%% Then, define a new pagestyle ``gtthesis''. I like this one better
%% but the Graduate Studies Office doesn't. :-(
